The characteristics of navigation lights on a power driven vessel includes sidelights, sternlight, masthead light, and all-round white lights. Navigation lights must be displayed from sunset until sunrise as well as anytime visibility is restricted.

Navigation lights on a boat must be turned on from sunset to sunrise and during periods of restricted visibility, such as fog or heavy rain. These lights help ensure that the vessel is visible to others and facilitate safe navigation. It’s important for operators to be familiar with the specific lighting requirements based on their type of vessel and local regulations. Always check local laws, as requirements may vary.
On power-driven vessels, navigation lights must be displayed in accordance with the International Regulations for Preventing Collisions at Sea (COLREGs). Typically, these vessels should show a white masthead light, red and green sidelights, and a sternlight when underway. The lights must be visible from specific angles and distances to ensure safe navigation and to signal the vessel's status to others. Proper use of navigation lights is crucial for preventing collisions during both day and night.
Those include red lights on the port side and green lights on the other.Depends on the size of the vessel. My tiny little 14 ft boat is only required to show a white light. The link at the bottom of this page will take you to a chart showing lights and visible ranges for different sizes.What is the size of the vessel? Refer to "Navigation rules" for vessel specific answers.
When underway, a power-driven vessel displays a combination of navigation lights: a white masthead light at the front, sidelights (green on the starboard side and red on the port side), and a white stern light at the rear. The masthead light is visible from ahead and extends 225 degrees, while the sidelights are visible from the side and ahead. The stern light provides visibility from behind. These lights help ensure the vessel is seen and identified by other vessels during nighttime or low visibility conditions.
Power-driven vessels must display specific navigation lights to indicate their presence and movement at night or in low visibility. Typically, they show a red light on the port side (left), a green light on the starboard side (right), and a white stern light at the rear. Additionally, a white masthead light is required, visible from ahead and at a distance. These lights help other vessels identify the type and direction of the power-driven vessel.
Generally they are masthead light, port and starboard steaming light and stern light. Others may be displayed depending on the length of the vessel and what duties it is carrying out.
On power-driven vessels, navigation lights must be displayed from sunset to sunrise and during restricted visibility. Typically, these vessels are required to show a white masthead light, sidelights (green on the starboard side and red on the port side), and a sternlight. The masthead light must be visible from a distance of 22.5 degrees ahead and the sidelights must be visible from 112.5 degrees on either side. Additionally, when at anchor, a power-driven vessel must display an all-round white light in the fore part of the vessel.
